showing .pps files using powerpoint 2000/powerpoint viewer2003

hello, im working on my project right now, and i have some problems in directly playing powerpoint show files(.pps) under wine. My .pps plays fine, but i want to play my .pps file directly after I click on the file.

i've used a script: (to open in powerpoint)
#!/bin/bash
wine "/home/user/.wine/drive_c/Program Files/Microsoft Office/Office/powerpnt.exe" "$@"


i've used a script: (to open in powerpoint viewer)
#!/bin/bash
wine "/home/user/.wine/drive_c/Program Files/Microsoft Office/Office/pptview.exe" "$@"


this script allows me to open powerpoint/powerpoint viewer after i click on a .pps file

this is what happens after i click my .pps file.
->it shows the powerpoint viewer (open file pop-up), but not playing the slideshow of that certain file.

how can I fix this to play the file directly without opening powerpoint or showing the (open file pop-up) in powerpoint viewer..

helps, comments or suggestions are greatly appreciated... Thank you...
